Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the backrest rotating shaft and the cushion rotating shaft of the zero-gravity automobile seat according to a preferred embodiment of the present invention are designed to be coaxial S to reduce the position of the backrest rotating shaft to the maximum extent, so that the change of the backrest profile relative to the human body is relatively gentle in the process of opening the backrest from the design position to the zero-gravity posture position, thereby ensuring good comfort, and the backrest assembly can be folded over relative to the cushion assembly alone, thereby satisfying the requirement of a user when the backrest needs to be adjusted alone.
As shown in fig. 2, the zero gravity vehicle seat includes a backrest assembly 1, a seat cushion assembly 2 and a backrest rotation motor 3, wherein the seat cushion assembly 2 includes an angle adjuster assembly 21, and the backrest rotation motor 3 is connected to the angle adjuster assembly 21 to drive the backrest assembly 1 to rotate and lock relative to the seat cushion assembly 2. Specifically, the backrest assembly 1 includes a backrest inner side wall plate 11 and a backrest outer side wall plate 12 which are opposed, the backrest inner side wall plate 11 is mounted on the inner side of the seat cushion assembly 2 by a backrest mounting step bolt 11a, the backrest outer side wall plate 12 is mounted on the outer side of the seat cushion assembly 2 by a backrest mounting bolt 12a, and the backrest rotation motor 3 is mounted on the outer side of the seat cushion assembly 2 by a backrest motor mounting nut 3 a.
As shown in fig. 3, the cushion assembly 2 includes a cushion wall plate assembly 22, a rear horizontal tube assembly 23, a slide rail assembly 24, a front link assembly 25, a zero gravity (Lounge) adjusting link assembly 26, a height adjusting motor 27 and a zero gravity adjusting motor 28, wherein the slide rail assembly 24 includes a slide rail rear ledge assembly 241, a slide rail middle ledge 242 and a slide rail front ledge assembly 243, the upper and lower ends of the rear horizontal tube assembly 23 are respectively pivoted with the rear end of the cushion wall plate assembly 22 and the slide rail rear ledge assembly 241, the upper and lower ends of the front link assembly 25 are respectively pivoted with the front end of the cushion wall plate assembly 22 and the front end of the zero gravity adjusting link assembly 26, the rear end of the zero gravity adjusting link assembly 26 is pivoted with the slide rail front ledge assembly 243, the front and rear ends of the height adjusting motor 27 are connected to the cushion wall plate assembly 22 and the rear horizontal tube assembly 23, and the front and rear ends of the zero gravity adjusting motor 28 are connected to the zero gravity adjusting link assembly 26 and the slide rail middle ledge 242.
The height adjustment principle of the seat cushion assembly of the zero-gravity automobile seat according to the present embodiment will be described with reference to fig. 4. The height adjusting motor 27 drives the rear horizontal tube assembly 23 to rotate around the slide rail rear convex frame assembly 241, and the rear horizontal tube assembly 23 drives the cushion wall plate assembly 22 to move forwards and upwards. The cushion wall assembly 22 drives the front link assembly 25 to rotate. Since the zero-gravity adjusting motor 28 does not work, the mechanism composed of the zero-gravity adjusting motor 28, the zero-gravity adjusting link assembly 26, the slide rail middle convex frame 242 and the slide rail front convex frame assembly 243 is in an interlocking state, and the front link assembly 25 can only rotate around the zero-gravity adjusting link assembly 26. In this way, the height adjusting movement of the seat cushion assembly 2 is simplified to the parallelogram movement.

The zero-gravity adjustment principle of the zero-gravity car seat according to the present embodiment is explained below with reference to fig. 6. The zero gravity adjustment motor 28 drives the zero gravity adjustment linkage assembly 26 to rotate around the slide rail front cam assembly 243. The zero gravity adjustment link assembly 26 rotates the front link assembly 25 about the seat cushion panel assembly 22. Because the height adjusting motor 27 does not work, the mechanism formed by the height adjusting motor 27, the cushion wall plate assembly 22 and the rear transverse tube assembly 23 is in an interlocking state, and the mechanism rotates around the sliding rail rear convex frame assembly 241 to drive the front connecting rod assembly 25 to move upwards. The backrest rotation motor 3 (see fig. 2) drives the angle adjuster assembly 21 to drive the backrest assembly 1 to synchronously rotate around the rear transverse tube assembly 23, wherein the synchronous movement of the backrest assembly 1 and the seat cushion assembly 2 is realized through module control programming, so that the zero gravity posture position of the automobile seat is finally realized.
